VW2010 MPEG-1, -2, -4 Audio/Video CODEC ChipChip
Product Brief
The VW2010 is a real-time MPEG-1, -2
and -4 audio/video/system CODEC chip
(simultaneous compression/ decompression,
or encode/decode) that fully complies
with ISO/IEC-11172-2, ISO/IEC-
13818-2, ISO/IEC-14496-2 and ITU-T
H.263. The VW2010 accepts uncompressed
ITU-R.BT-656 video and I2S
audio, compresses the video into MPEG-
1, -2, -4 or H.263 formats, compresses the
audio into MPEG-1, MPEG-2, MP3,
AAC or AC-3 audio formats, and outputs
them as transport streams for network
applications or program streams for storage
applications. In addition, the VW2010
accepts an MPEG bitstream input, and
outputs ITU-R.BT-656 video. It also
accepts an MPEG-1, MPEG-2, MP3,
AAC or AC-3 audio bitstream input, and
outputs audio through I2S, S/P-DIF or
IEC-61937.
